A profound study of a multilevel boost converter-fed induction heating using ADC control with guaranteed ZVS operation avoids the use of an EMC filter at the source, variable DC-link voltage, and high output RMS voltage. DC-link voltage is controlled by varying the duty cycle of MBC. By the control of the DC-link voltage, the heat in the workpiece can be changed. This gives an additional benefit over the switching frequency control of the inverter, for controlling the heat in the workpiece. Simulated outputs validate the performance and controllability of this scheme. As per the simulation results, output current obtained is 33-69 A. So, it can be preferred in all industrial applications for Induction Heating. The proposed configuration has merits like independent control, high voltage gain, high input power factor, high reliability, and less complexity.
